The hacker who stole 20 million (about $17 million) OP tokens from the Wintermute crypto platform returned 17 million coins to the Optimism contract address, according to PeckShieldAlert. Before that, he sent 1 million tokens to the creator of Ethereum, Vitalik Buterin. Another 1 million were sold immediately after the theft.
Optimism is an Ethereum scaling solution that improves the governance structure of the network. The community cryptocurrency was released on June 1, and 5% of all tokens were distributed to approximately 250,000 users.
The Optimism platform has hired Wintermute as a liquidity provider to make it easier for users who purchase OP tokens to participate in collective governance. As a partner supporting the project, the company was given a temporary grant of 20 million coins on the eve of the distribution.
On the evening of June 10, the attacker still had 1 million OP left. Initially, Wintermute offered the hacker a refund within one week, while promising to take no legal action.
